All operations, other than program-flow instructions, are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand. Program Counter PC/R0 Stack Pointer SP/R1 SR/CG1/R2 Status Register Constant Generator CG2/R3 General-Purpose Register R4 General-Purpose Register R5 General-Purpose Register R6 General-Purpose Register R7 General-Purpose Register R8 General-Purpose Register R9 General-Purpose Register R10 Instruction Set General-Purpose Register R11 The instruction set consists of 51 instructions with three formats and seven address modes. Each instruction can operate on word and byte data. Table 3 shows examples of the three types of instruction formats; Table 4 shows the address modes. General-Purpose Register R12 General-Purpose Register R13 General-Purpose Register R14 General-Purpose Register R15 The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock. Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and constant generator respectively. The remaining registers are general-purpose registers. Peripherals are connected to the CPU using data, address, and control buses and can be handled with all instructions. Table 3.

An interrupt event can wake up the device from any of the five low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program. The following six operating modes can be configured by software: • Active mode (AM) – All clocks are active. • Low-power mode 0 (LPM0) – CPU is disabled. – ACLK and SMCLK remain active. MCLK is disabled. • Low-power mode 1 (LPM1) – CPU is disabled ACLK and SMCLK remain active. MCLK is disabled. – DCO dc-generator is disabled if DCO not used in active mode. • Low-power mode 2 (LPM2) – CPU is disabled. – MCLK and SMCLK are disabled. – DCO dc-generator remains enabled. – ACLK remains active. • Low-power mode 3 (LPM3) – CPU is disabled. – MCLK and SMCLK are disabled. – DCO dc-generator is disabled. – ACLK remains active. • Low-power mode 4 (LPM4) – CPU is disabled. – ACLK is disabled. – MCLK and SMCLK are disabled. – DCO dc-generator is disabled. – Crystal oscillator is stopped. 8 Copyright © 2007–2011, Texas Instruments Incorporated MSP430F21x2 SLAS578H – NOVEMBER 2007 – REVISED JUNE 2011 www.ti.com Interrupt Vector Addresses The interrupt vectors and the power-up starting address are located in the address range of 0xFFFF to 0xFFC0. The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence. If the reset vector (located at address 0xFFFE) contains 0xFFFF (for example, if flash is not programmed), the CPU goes into LPM4 immediately after power up. Table 5.

Access to the MSP430 memory via the BSL is protected by user-defined password. For complete description of the features of the BSL and its implementation, see the MSP430 Programming Via the Bootstrap Loader User’s Guide, literature number SLAU319. Table 11. BSL Function Pins BSL FUNCTION PW PACKAGE PINS RHB, RTV PACKAGE PINS Data transmit 22 - P1.1 22 - P1.1 Data receive 10 - P2.2 8 - P2.2 Flash Memory The flash memory can be programmed via the JTAG port, the bootstrap loader, or in-system by the CPU. The CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include: • Flash memory has n segments of main memory and four segments of information memory (A to D) of 64 bytes each. Each segment in main memory is 512 bytes in size. • Segments 0 to n may be erased in one step, or each segment may be individually erased. • Segments A to D can be erased individually, or as a group with segments 0 to n. Segments A to D are also called information memory. • Segment A contains calibration data. After reset, segment A is protected against programming and erasing. It can be unlocked, but care should be taken not to erase this segment if the device-specific calibration data is required.

For complete module descriptions, see the MSP430x2xx Family User's Guide (SLAU144). Oscillator and System Clock The clock system is supported by the basic clock module that includes support for a 32768-Hz watch crystal oscillator, an internal very-low-power low-frequency oscillator, an internal digitally-controlled oscillator (DCO), and a high-frequency crystal oscillator. The basic clock module is designed to meet the requirements of both low system cost and low power consumption. The internal DCO provides a fast turn-on clock source and stabilizes in less than 1 µs. The basic clock module provides the following clock signals: • Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high-frequency crystal, or the internal very-low-power LF oscillator. • Main clock (MCLK), the system clock used by the CPU. • Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules. The DCO settings to calibrate the DCO output frequency are stored in the information memory segment A.

Digital I/O There are four 8-bit I/O ports implemented—ports P1, P2, and P3: • All individual I/O bits are independently programmable. • Any combination of input, output, and interrupt condition is possible. • Edge-selectable interrupt input capability for all eight bits of port P1 and P2. • Read/write access to port-control registers is supported by all instructions. • Each I/O has an individually programmable pullup/pulldown resistor. The MSP430F21x2 devices provide up to 24 total port I/O pins available externally. See the device pinout for more information. Watchdog Timer (WDT+) The primary function of the WDT+ module is to perform a controlled system restart after a software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed in an application, the module can be disabled or configured as an interval timer and can generate interrupts at selected time intervals. ADC10 The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion result handling allowing ADC samples to be converted and stored without any CPU intervention. Comparator_A+ The primary function of the comparator_A+ module is to support precision slope analog-to-digital conversions, battery-voltage supervision, and monitoring of external analog signals.

Frequencies below the MIN specification set the fault flag, frequencies above the MAX specification do not set the fault flag, and frequencies in between might set the flag. Measured with logic-level input frequency, but also applies to operation with crystals.

The dynamic impedance of the reference supply should follow the recommendations on analog-source impedance to allow the charge to settle for 10-bit accuracy. The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced accuracy requirements. Under this condition, the external reference is internally buffered. The reference buffer is active and requires the reference buffer supply current IREFB. The current consumption can be limited to the sample and conversion period with REBURST = 1. The accuracy limits the maximum negative external reference voltage.

When activated, a fuse check current, ITF , of 1 mA at 3 V, 2.5 mA at 5 V can flow from the TEST pin to ground if the fuse is not burned. Care must be taken to avoid accidentally activating the fuse check mode and increasing overall system power consumption. When the TEST pin is again taken low after a test or programming session, the fuse check mode and sense currents are terminated. Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if TMS is being held low during power up. The second positive edge on the TMS pin deactivates the fuse check mode. After deactivation, the fuse check mode remains inactive until another POR occurs. After each POR the fuse check mode has the potential to be activated. The fuse check current flows only when the fuse check mode is active and the TMS pin is in a low state (see Figure 32). Therefore, the additional current flow can be prevented by holding the TMS pin high (default condition). Time TMS Goes Low After POR TMS ITF ITEST Figure 32. Fuse Check Mode Current NOTE The CODE and RAM data protection is ensured if the JTAG fuse is blown and the 256-bit bootloader access key is used. Also, see the Bootstrap Loader section for more information.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
